Brake Thermal Modeling
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
our engineers are well-prepared to employ FEA and CFD tools to capture all modes of heat transfer from the system: radiation, conduction and convection. Our simulation methods include all transient braking events whether that is a high-speed track test or any transient customer driving profile. Our engineers can help you identify ways to reduce the mass of your system while improving thermal performance or exploring highly wear-resistant materials.
Using FEA and CFD softwares, Enteknograte engineers quickly produce accurate models of brakes, clutches, or other friction devices. We deliver comprehensive engineering reports, and in-depth aero-thermal analysis for the entire brake system.
Why we use Coupled FEA-CFD?
Finite Element Analysis (FEA) is a powerful and well recognized tool used in the analysis of heat transfer problems. However, FEA can only analyze solid bodies and, by necessity thermal analysis with FEA is limited to conductive heat transfer. The other two types of heat transfer: convection and radiation must by approximated by boundary conditions. Modeling all three mechanisms of heat transfer without arbitrary assumption requires a combined use of FEA and Computational Fluid Dynamics (CFD).
With using CFD based design optimization solutions serve as an important link for our clients to realize their product promise right from concept to realization. Our team of CFD engineers in conjunction with experienced FEA Engineers for FSI and complicated industrial multiphysics problem is delivering solutions to major engineering verticals globally.

Fluid Structure Interaction for Thermal Analysis
Fluid Structure Interaction (FSI) calculations allow the mutual interaction between a flowing fluid and adjacent bodies to be calculated. This is necessary since all real structures are flexible, especially those that are large or subject to high fluid loads. The body forces generated by fluids flowing are highly sensitive to the shape and curvature of adjacent surfaces.
By coupling a CFD solver and the FEA solver, the deformation of a body resulting from the fluid loads and the subsequent modification of the flow field due to the newly deformed geometry can be computed iteratively. This technique allows aeroelastic instabilities such as flutter, to be detected and avoided early in the design cycle. Similarly, where structures are subjected to cyclic fatigue loading, such as rotor-stator interaction in compressor applications or vortex shedding around civil structures, these load effects can be accurately quantified to allow the fatigue life of the structure to be assessed.
Simulating the thermal performance of a product early in the design phase can save large amounts of time and money by getting the design of the early prototypes right from a thermal management standpoint, thus reducing the need for additional prototypes that might otherwise be required to diagnose and correct thermal issues. Simple computational fluid dynamics (CFD) software can be used to analyze thermal issues such as determining how heat is transferred through a fluid. But many problems are more complex, such as those that involve multiple mechanisms of heat transfer, where heat is transferred through both solids and structures.
Cases in which the fluids and structures involved in heat flow are closely coupled, so that thermal deflection of the structures affects the fluid flow, are also challenging. Engineers often need to understand how heat is transferred by a number of different mechanisms through a complicated interconnected system in order to understand how their product or process will perform under a given set of conditions. This point is one of the applications of FSI simulation with Coupled CFD-FEA method.
As in isolated FEA and CFD one of the most profound benefits of FSI analysis is the ability to conduct comprehensive, multi-point optimization of designs. This process allows us to optimize a design to a given set of performance parameters and can be used to tune frequencies, or maximize fatigue life or avoid harmful resonance.
